Native Spanish speaker here.
Directly translated as “I want you” but it is often used as a
casual “I love you” among Spanish speakers. Usually used with
parents, siblings, friends, etc.
Meanwhile “Te Amo” is considered very intimate and usually only used with a partner. Even then it may only be said sparingly or during intimate moments such as the first
time someone says I love you. Spanish speakers usually revert back to using “te quiero” or even saying “i love you” if both parties speak mostly English
